A Gram-negative bacterium, designated DCY13T, was isolated from soil of a ginseng field in South Korea. Comparative analysis of 16S rRNA gene sequences showed that strain DCY13T shared the highest sequence similarity (95.0 %) with Sediminibacterium salmoneum NBRC 103935T and 87.6–91.4 % sequence similarity with other members of the family Chitinophagaceae . Cells were non-spore-forming rods, catalase- and oxidase-positive, motile by gliding and facultatively anaerobic. The only respiratory quinone was menaquinone 7 (MK-7) and the major fatty acids were iso-C17 : 0 3-OH, iso-C15 : 0 and iso-C15 : 1 G. The G+C content of the genomic DNA was 47.5±1.0 mol%. In addition to phosphatidylethanolamine, the major polar lipids were two unidentified aminophospholipids, one unidentified aminolipid and three unidentified polar lipids. The major cell-wall sugars were ribose, xylose and galactose. It is proposed that strain DCY13T represents a novel species in the genus Sediminibacterium , for which the name Sediminibacterium ginsengisoli sp. nov. is proposed. The type strain is DCY13T ( = KCTC 12833T  = JCM 15794T  = DSM 22335T). Emended descriptions of the genus Sediminibacterium and of Sediminibacterium salmoneum are also proposed.

A Gram-staining-negative, rod-shaped, gliding and pale-pink-pigmented bacterium, designated strain ZLM-10T, was isolated from a soil sample collected from an arid area in Xinjiang province, China, and characterized in a taxonomic study using a polyphasic approach. The novel strain grew optimally at 30–37 °C and in the presence of 2 % (w/v) sea salts. The only respiratory quinone detected was MK-7 and the major cellular fatty acids were summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c), iso-C15 : 0 and iso-C17 : 0 3-OH. The polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine, an unidentified aminolipid and two unidentified aminophospholipids. The DNA G+C content was 45.4 mol%. Flexirubin-type pigments were not produced. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain ZLM-10T was a member of the phylum Bacteroidetes and appeared most closely related to Cesiribacter roseus 311T (90.2 % sequence similarity), Marivirga sericea LMG 13021T (89.2 %), Cesiribacter andamanensis AMV16T (89.1 %) and Marivirga tractuosa DSM 4126T (89.1 %). On the basis of phenotypic and genotypic data and phylogenetic inference, strain ZLM-10T should be classified as a novel species of a new genus in the family Flammeovirgaceae , for which the name Nafulsella turpanensis gen. nov., sp. nov. is proposed. The type strain of the type species is ZLM-10T ( = CCTCC AB 208222T = KCTC 23983T).

Polyphasic Characterization

Strain M2T, isolated from marine sediment collected at Jeju Island, was an aerobic, Gram-stain-negative, oxidase- and catalase-positive, motile, rod-shaped bacterium that formed circular, raised, yellow colonies. Strain M2T grew at 15–42 °C, pH 5.5–9.0 and with 1–9 % (w/v) NaCl. Phylogenetic analysis based on its 16S rRNA gene sequences indicated that strain M2T was closely related to Kineobactrum sediminis F02T (98.0 % sequence similarity). Ubiquinone-8 was determined to be the sole respiratory quinone. Summed feature 3 (C16 : 1  ω6c/C16 : 1  ω7c) and summed feature 8 (C18 : 1  ω7c/C18 : 1  ω6c) were identified as the predominant fatty acids. The DNA G+C content and digital DNA–DNA relatedness between strain M2T and K. sediminis F02T were 60.7 mol% and 19.5 %, respectively. Phosphatidylglycerol and phosphatidylethanolamine were identified as the major polar lipids. Thus, polyphasic characterization revealed that strain M2T represents a novel species in the genus Kineobactrum , for which the name Kineobactrum salinum sp. nov. is proposed. The type strain is M2T (=KCTC 72815T=VTCC 910108T).

The genomic DNA G+C content was 42.4 mol%. Strain MMS17-SY002T could be distinguished from related species by the combination of trypsin, α-chymotrypsin, acid phosphatase, naphthol-AS-BI-phosphohydrolase, α-galactosidase, β-galactosidase and β-glucosidase activities. The orthologous average nucleotide identity between the genomes of strain MMS17-SY002T and M. jejuensis and that between the strain and M. marianensis A6B8T were 73.26 and 73.33%, respectively, thus confirming the separation of the strain from related species at species level. Based on the phenotypic, phylogenetic, chemotaxonomic and genomic characterization, MMS17-SY002T should be recognized as a novel species of the genus Muriicola , for which the name Muriicola soli sp. nov. is proposed. The type strain is MMS17-SY002T (=KCTC 62790T=JCM 32370T).
